Consider a cmos process for which lmin=0.25um, tox=6nm, mn=460 cm2/v s and vt=0.5v (from problems 5.10)

a,) find cox, and kn’
b.) for an nmos transistor with w/l=15um/0.25um, calculate the values of vov, vgs, and vdsmin needed to operate the transistor in the saturation region with a dc current id=0.8ma.
c.) for the device in (b), find the value of vov and vgs required to cause the device to operate as a 500 w resistor for very small vds.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
